CONTAX contactor

Contactors are electromechanically controlled switches used
to control single or multi-phase (high) power loads while the control
itself can be (very) low power.

Applications

Switching of lighting, heating-equipment, motors for pumps
and fans, ...

Day and night contactors are used mainly in ­combination
with dual-tariff applications to allow high-energy-loads (i.e.
electrical water heaters, ­accumulation heaters) only to consume energy
during the low-tariff period.

A forced-on, forced-off, auto-switch allows to overrule the
normal operation of the DN-contactor at all times.

Features

Except for the 20A version, all contactors have DC coils,
resulting in an absolutely noise-free, real silent operation: 50 or
60Hz noise generation by the contactor is impossible. As all DC coil
contactors have an internal diode ­rectifier bridge, they all can be
operated by both DC and AC power supplies. The built-in varistor
protects the coil against an overvoltage of up to 5kV.

The switch position of the contactor is visualised through
an indicator flag.

The loss-proof safety terminals are equipped with Pozidriv
screws and have IP20 protection degree. Add-on auxiliary contacts as
well as spacers and ­sealing pieces are available.
